Plans for covid vaccine effectiveness/impact studies

Plans for covid vaccine effectiveness/impact studies

Dear colleagues,
 
After COVID-19 vaccines are introduced into countries, it will be vital to generate real-world data on vaccine effectiveness and impact, as many questions will remain unanswered by the clinical trials.  Studies will likely be done in a variety of countries, in a variety of populations, and using a variety of study designs.  We are reaching out to you as you or persons you know/work with might be planning to do such studies.  WHO is undertaking a scoping exercise to understand who is planning COVID-19 vaccine effectiveness and impact studies, where they are being planned, and the key characteristics of such studies. This information will help WHO to understand the future availability of data to inform global policy and the gaps that need to be filled. We understand that plans are still being made and are subject to change; thus, we will likely be reaching out again in the future to request an update. Basic information on the studies planned will be shared through the WHO website (e.g. country of study, study design, objective of the study).
 
If you are planning on doing a COVID-19 vaccine impact or effectiveness study, please fill out this electronic form with any relevant details.  This form will take less than 5 minutes  of your time.
 
Please forward this email to colleagues who might be conducting such studies. Questions can be addressed to This email address is being protected from spambots. You need JavaScript enabled to view it.
